[ RadSafe ] Airfilter gamma spectrum 1986

[Brennan, Mike (DOH)]

The difference between current data and Egyptian hieroglyphics is that in a thousand years the hieroglyphics will still be readable.  Indeed, it may only take about 5 years for modern data to be unreadable.  

2 operating system changes = 1 electro-magnetic pulse attack

Peter,

May I remind you, that you yourself have in the course of your work for the infamous "Gammameßstelle" in Vienna recorded quite a few spectra - didn't you save them..... (No pun intended, I am just teasing you...) You should know that my laboratory has collected hundreds if not thousands of spectra during the "critical time". I only remember that E Henrich has changed all the time the storing routines, going from PDP 11 RL01 to RL02 etc. I do not know what happened with all those backup media, but I am rather sure that they cannot be read anymore. I have not bothered to follow the tracks, but if anybody might give you an answer when it comes to Austria it might be Mr.
Katzelberger at AGES. Otherwise I would recommend to contact for instance the Swedish Radiation Protection Institute (SSI) or the Finnish one (Säteiliturvallisuskeskus), where high concentrations were recorded. The same is true for Munich-Neuherberg and many others also in some Eastern parts of Europe. 

For me it is a confirmation of my scepticism toward the more than rapid development of digital storage techniques because at every change information gets lost. 

I heard that you have a new job? Gratulations!

Best wishes,

Franz

Betreff: [ RadSafe ] Airfilter gamma spectrum 1986

Colleagues:

I am in search for a high resolution gamma spectrum of an airfilter of around 1 May 1986, in digital format. Activity load, air volume or sampling time should be rather high, so that as many "exotic" lines of the Chernobyl cloud as possible are visible. (Thus this request is probably mainly directed to colleagues in Central and Eastern Europe.)

I would need it in txt format: (channel #,  counts). Energy cal. would be a nice addition, but if unavailable I can find it out myself from the spectrum. I am not interested in quantitative results (Bq/m^3), so sampling time, air flow and eff. cal. are not of interest.

I need it for a report for demonstration of what a gamma spectrum in such a situation may look like. Unbelievably, although so many measurements of that kind were made, it is difficult to find any in *still readable* digital format. (A case for archeology of science.)

Thanks for any hint.

Peter
